Acts 17:13

But when the Jews of Thessalonica had knowledge that the word of God was proclaimed of Paul at Berea also, they came thither likewise, stirring up and troubling the multitudes.

The fundamental antipathy between darkness and light, the implacable hatred of Satan for the truth, was there evidenced by those relentless foes of the gospel, who at such trouble and expense to themselves exploited every opportunity to slander and oppose Paul's preaching of the gospel. As Walker said, "The hounds of persecution bayed on Paul's trail from Thessalonica to Berea."[23] They tracked him from city to city; and, as Paul thought upon this, he must have remembered his own days as a persecutor.
